Wisconsin Gov. Scott Walker is running for the Republican nomination for president, but he certainly came up with an idea nobody else would have thought of. He wants a wall on the entire U.S.-Canadian border, which is the dumbest thing I've heard of in some time. The racists down near Mexico can't build the wall of their dreams, and with a similar length of land to cover this other wall would be quite the pain for taxpayers. But unlike the Mexico wall, this one wasn't to keep out immigration, but to prevent terrorists from getting through. He honestly thinks a wall will stop that? It will just hurt the economic relationship between the United States and Mexico when that wall slows everything down.
